Well I have the Phantom Hour Glass that I'm never going to pick up again and Unreal Tourney 3 (PC)... But other than that I find I don't have to many games I shelf forever, and the ones I did I foolishly resold to gamespot for 5$

No, you normally can't give away your games. It's only if you wind up with doubles by buying a pack of games or something. I have 2 copies of Half-life 2. 1 I bought on it's own and the other came with the Orange Box.
